Excel 2003 worksheet opened in Exceel 2007. Data is 15 (0, 15,30, 45) minute
readings by hr. by date. When making chart from pivot table, area chart
shows date, hour, and minute labels for day 1 only, day 2 - end of chart only
show munute labels. Missing are Category labels for date and hour.

Thought an example might help.
Chart data is from Pivot Table
